Abstract: An electronic device, detects a touch input. After a latency period, the device delivers to an application a sequence of input events that represent the touch input, including, in sequence: a first input event that represents the touch input at a first input time and is delivered at a first delivery time, a second input event that represents the touch input at a second input time and is delivered at a second delivery time, and a third input event that represents the touch input at a third input time and is delivered at a third delivery time, a time interval between the second input time and the second delivery time is smaller than a time interval between the first input time and the first delivery time, and a time interval between the third input time and the third delivery time is smaller than the time interval between the second input time and the second delivery time.

Abstract: An electronic device such as a portable electronic device may have display with a capacitive touch sensor. A cover may have a front portion and a rear portion that bend along a bend axis. The front portion may overlap the display when the cover is closed. Conductive structures such as a patterned conductive layer having elongated strips of conductive material separated by gaps or another predetermined pattern may be formed in the front portion of a cover or other portion of a cover that overlaps the display and capacitive touch sensor when the cover is closed. Control circuitry in the device can gather capacitance images with the touch sensor and can detect when the cover has transitioned from open to closed or from closed to open from whether the predetermined pattern becomes present or becomes absent in the capacitance images.

Abstract: In some embodiments, an electronic device in communication with a display and a touch-sensitive surface displays a user interface, and while displaying the user interface, the electronic device receives touch input comprising a contact detected on the touch-sensitive surface. In some embodiments, in response to receiving the touch input, and in accordance with a determination that the touch input satisfies first criteria, wherein the first criteria include a requirement that the contact continues to be detected in a predefined region of the touch-sensitive surface for longer than a time threshold, the electronic device displays a first indication that further input of a first type detected at the touch sensitive surface will cause the device to display a first system user interface. In some embodiments, in accordance with a determination that the touch input does not satisfy the first criteria, the electronic device forgoes displaying the first indication.

Abstract: Touch input processing for touch-sensitive devices can be improved by filtering unintended contact detected on a touch-sensitive surface. In wet environments in particular, water on the touch-sensitive surface can be erroneously detected as touch input and degrade touch performance. In some examples, input patches can be classified as touch patches or non-touch patches prior to computationally-intensive touch processing. Filtering out unintended touches classified as non-touch patches can reduce processing requirements and save power. Additionally, classifying input patches can improve touch performance in wet environments. In some examples, input patches can be classified as touch patches or non-touch patches based on characteristics of edge touch nodes. In some examples, input patches can be classified as touch patches or non-touch patches based on a state-based signal threshold.

Abstract: Reconstruction of an original touch image from a differential touch image is disclosed. Reconstruction can include aligning columns of the differential touch image relative to each other and aligning the image to a baseline DC value. The column and baseline alignment can be based on the differential image data indicative of no touch or hover, because such data can more clearly show the amount of alignment needed to reconstruct the original image. The reconstruction can be performed using the differential image data alone. The reconstruction can also be performed using the differential image data and common mode data indicative of the missing image column average.

Abstract: The rejection of undesired touch events on a touch surface is disclosed. A weighted meta-centroid of all touch events can be computed. In some examples, touches can be weighted inversely to their size and distance to the nearest neighboring touch. In some examples, touches can be weighted based on the size of their minor radii. A meta-ellipse can be fit to the weighted touch events. In some examples, the major axis of the meta-ellipse can be used to determine the orientation of a user's hand to reject undesired touches. In other examples, touches within the meta-ellipse can be rejected.

Abstract: This relates to a method of extrapolating proximity information to generate a border column or row of touch nodes (also known as touch pixels) and then fitting an ellipse to the contact patch including the extrapolated border touch nodes. Additionally, a contact can be identified as a thumb based on both its major axis and its distance to an edge of the touch sensing surface.

Abstract: In one aspect, the present disclosure relates to a method and system for performing an adaptive make/break detection technique including adapting make and break thresholds based on the sum of all signals measured on display electrodes when the sum is lower than a respective filtered sum value. The filtered sum values are produced by a fast and slow filter, which correspond to the break and make thresholds respectively. By performing this method, the accuracy of detecting stylus touch-down and lift-off from a display can be improved, even in the presence of confounding factors such as variation in stylus manufacture, user grip, stylus angle, and water on the display.
